ROOFING SHEET.

, Application filed March 5, 1921, Serial No. 449,766. Renewed December 29, 1922.

To all whom it may concern Be it known that I, JAMES F. DAUT, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and State of West Virginia, have invented certain new. and useful Improvements in Roofing Sheets, of which the following is a specification.

This invention relates broadly to sheetmetal roofing, and more specifically to a joint for such roofing.

The primary object of the invention is to provide a joint of the V-crimp type which shall be leak proof and which shall possess great strength and stability.

A further object is to provide a joint for sheet-metal roofing which not only has the members or parts thereofso arranged and related that they effectually guard against leakage or seepage of water thereunder and are adapted to resist distortion or crushing from such strains as are ordinarily imposed thereon, but also a joint which involves a minimum number of bends or angles and which, consequently, may be made conveniently and easily with dies of simple and economical forms.

With these and other objects in view, the invention resides in the features of construction which will hereinafter be fully described, reference being had to the accompanying drawings, in which lgure 1 is a view showing, in perspective, a roofing sheet constructed in accordance with my invention and forming joints at its opposite lateral edges with similar sheets; and- Figure 2 is an enlarged section of the joint.

Referring to said drawings, 1 indicates a roofing sheet which is shaped along one of its lateral edges to provide a vertical supportin leg 2, a relatively narrow horizontal tal e or seat 3, and an inclined leg 4, said seat 3 joining the upper ends of said legs 2 and 4. The opposite lateral edge of the sheet is shapedto provide an inclined leg 5, a horizontal table 6 and an inclined terminal leg 7 said table joining said legs 5 and 7.

Each sheet 1 is designed to form a close 7 water-tight joint with an adjacent sheet of like form, the edge of one sheet having the two inclined legs being disposed in overlying or overlapping relation to the edge of at a spaced distance from the fo o t of the vertical leg 2 of the latter.

The upstanding rib 8 and the leg 7 co operate in the formation of a barrier whereby the passa e of water is in large measure prevented. owever, that portion of the underlying sheet which is located between said rib and the upright leg 2 constitutes the bottom of a trough 9 'for the reception of seepage and whereby such seepage is drained away from the joint. Furthermore, the chamber afforded between the legs 2 and 7 provides for a more or less free circulation of air whereby moisture which may collect in the troughis quickly dissipated.

Obviously, due to the fact that the legs 2 and 7 lie wholly out of contact one with the other, or out of overlapping relatlon,

there is no possibility of the passage of water by capillary attraction to the level of the tables.

The upright leg 2 with the closely engaging legs 4 and 5 form substantial supporting means whereby the joint is rendered capable of resisting strains imposed thereon either by the blows required to drive fastening nails through the engaged tables or by the weight of persons walking upon the roof.

A decided advantage possessed by the structure described is that both the legs 5 and 7 of the joint are firmly braced, the former by the inclined leg t and the latter by the rib 8. Further, the formation of the jomt members provides for more than ordiprising a lapped member composed of an upright leg, an inclined leg and a narrow horizontal table connecting said legs, said inclined leg being formed along the terminal edge of the sheet,'an upstanding rib in the sheet at a spaced distance from said up- 7' right leg, and an overlapping member formed on an adjacent sheet and composed of two inclined legs and a table connecting said legs, oneof said legs of the overlapping member being in seated relation to the inclined leg of the lapped member, the table of the overlapping member being seated on the table of the lapped member, and the other leg of the overlapping member being disposed With its lower edge in closely abutting relation with the outer side of the rib on the lapped member, said rib acting as a support for the last mentioned leg of the overlapping member and cooperating with the upright leg of the lapped member to 15 form a trough for the drainage of moisture. In testimony whereof, I afiix my signature in presence of two subscribing Witnesses.
